I do anything for you

What would you do if you reject the one that confessed to his or her love to you? Would you give his or her a chance or forget til it's too late? If you had your eyes on someone but someone else had eyes for you would you know about it or would you just ignore it and be with the person you think you love? Knuckles certainly made a mess of things. He dated Shadow (while Sonic had a thing for Knuckles but failed to get his attention due to Knuckles being mean to him and all) until he passed away and Sonic kinda tried to be there for him after the funeral but ended badly. Now Sonic has disappeared. Is he dead or alive??
